Sony Discman D-311. Includes original box and all original accessories plus an extra set of bud headphones (the ones with the remote on them). Original rechargeable battery is bad so that I threw out. It does include the AA battery adapter though.
Discman works like new. (Sony just replaced the main laser and motor assemblies). I can include a copy of the receipt from sony and the old parts to verify if u want.
My price is $400 or willing to trade for headphone amp.
